I understand the need for this, but don't think this is the right way of doing it.

Query::getResults() will now return an array or a Query. For pure index queries, it will return an array, while for mixed queries it will return an object.

Are you passing the result set to the paginator, or the query object? The original code-base I forked from had an event subscriber for KNP pager, perhaps you can have a look at how that was implemented?

Sorry, but I am not going to implement this pull request.
